Who does lots of part/light throttle driveability stuff on the dyno? It can be used for that, but takes a long time and lots of money, dynos are...

Everything sounds fine other than the remaining question about fuel pressure.

Tuning on the dyno was done with a wideband installed and the numbers were almost perfect.

Both engines had MDS and honestly I left it in as I didn't want to change the cam out(new engine only had 33k miles). Only upgraded the oil pump to...

Combine the tune with a eFlex box from me and you will see 25-30% mid range torque increase Otherwise he is correct… todays gas is shit Thank...

The only difference between cam profiles I can think of is that MDS-equipped engines have slightly larger lobes for the MDS cylinders in the truck...

If FAST is now supplying legit data thet they generated themselves using real legit test equipment or hired someone reputable to generate that data,...

You can easily remove the intervals in notepad

An injector cannot be a 'performance upgrade' and also not require changing the tune. If no changes are needed then it's just a straight up stock...

Gonna be looking at all of them while checking compression. Break in oil was changed at 250 miles and went to 5w40 syn. Break in oil is straight oil....

Look at a couple spark plugs too, they always tell a story, along with making sure the oil hasnt been flooded with gas

You'd likely have much better luck with a good throttle body. I highly recommend the NW throttle bodies. I understand you ported your IAC...

I’ll log injector pulse width tomorrow. Everything on this engine is new. Fresh build with 2 tanks of fuel through it. I’ll double check everything...

It's MAF-only right now due to that dynamic setting. Not ideal. Is there a number on the injector? Did they come with data?

Thank you.

I am not entirely convinced this is a tune related issue at this point, i think it started as mechanical issue that was tuned to try and fix it. I...

How does this tune look? 2003 Cobra 2.8 keen Bell 22psi

just going off of what the log is showing. Im lost. its also on the OEM narrowband o2s

How does one remove a polling interval? He mentioned he has them polling at the preset interval of .2 seconds.

veeefour I have an f150 coyote pcm. Should i just use the stock strategy and have the pats removed?

That shouldn't even run on gas with a commanded AFR that low, 6.4 is stoich for methanol... since it is running, commanded AFR is being used to...

AFR Commanded on startup is 6.27 and after about 6 seconds it starts to lean out to 12.1 to 13.09 until it reaches 110 degrees ECT and then richens...

They are the blue GM 36lb and fuel pressure is set to 58 with a Holley regulator. In regard to your last response is there a reason that he would...

what i cant wrap my head around is how it runs fine with the fueling tables AFTER 110 degrees. Its only before 110. Theres gotta be something or...

no, not really. spits and sputters and falls on its face. I loaded the Original edit file and logged.

Which 36lb injectors? During startup cranking VE is used against the fuel injector data. IFR is 36.2. Typically, a 36lb injector is 3bar. On...

Mistakes were made and I should have known better, but that issue was already addressed, I ported the IAC passage and reclocked the tps. It works as...

Are you able to keep it running with some light throttle?

There's no "tricking" emissions tests involved. I guess you "forgot" that. It's limited to the 4800 RPM spark table, along with a couple other...
